AP105-DF61-2226S(61)

The AP105-DF61-2226S(61) is a type of circuit protection device that is commonly used in a variety of applications. This device is a microprocessor based, solid state, dual-feedback, circuit protection device. It is suitable for use as an overload protection device in a range of industrial and commercial applications.

The device is designed to provide high speed, low pass filtering and overload protection to circuits fed from power sources of various types. It is also able to delay the opening of circuits, thus providing a longer time delay before circuit interruption, which is particularly advantageous in circuits supplying loads which take a while to reach their operating parameters.

The working principle of the AP105-DF61-2226S(61) is based on a combination of two circuits: an analog fast-feedback circuitry, which monitors current load conditions, and an analog delay-feedback circuitry, which is designed to provide extra current protection in addition to the fast-feedback circuitry, thus resulting in an extended time delay protection. The analog fast-feedback circuitry consists of a fixed sensing resistor and one or two zener diodes. The sensing resistor is used to detect the current overload level in the circuit and is connected in series with the load.

The analog delay-feedback circuitry consists of one or two bipolar junction transistors (BJTs). The BJTs are connected with the load in such a way, that the current flow is constantly monitored. When the current flow exceeds the overload level set in the device, the feedback circuitry will activate the BJT gates, thereby setting into motion the delay for circuit interruption.

The AP105-DF61-2226S(61) is suitable for use in a wide range of power source applications. These include AC, DC, and AC/DC sources with up to 600V of input power. This device is also able to provide a greater amount of overload protection than many other types of circuit protection devices due to its two stage protection system. Additionally, the device is designed to be tamper-proof and requires no additional components to be added to the circuit.

The AP105-DF61-2226S(61) is an ideal choice for any application where protection from overloads and short circuits is necessary. This device is well suited for industrial, commercial, and residential applications alike, and will offer exceptional protection for any connected circuit.
